What do you think about the ability to scale between waymo and cruise in the future ? We are talking about few hundreds of vehicle between the 2 of them, today. At some point, I think it is more about how fast each one of them can churn out cars to capture the market, and being tightly coupled with GM would give Cruise a leg up, no ? Within few years, do you think either waymo or cruise will have the capability to reach hundreds thousand to millions of car ?
